In temperate rainforest, the dominant plant form is often coniferous trees (source). However, coniferous trees are also the dominant plant form in a very different climate and form a different biome ...

Chitin is considered the most abundant polymer after cellulose (e.g., Rinaudo, 2006).
Does anyone know of specific biomass estimates in literature, probably also differentiating between terrestrial ...
